struct.- a suitable framework for supporting the diHerent mechanisms required to form a wire nail. The table or framework as preferably constructed is formed of a casting havg ing a top 1 and depending legs 2 2, these legs "being braced by integralbraces 3. The end of the top of the table, which willbe herein- !after referred to as the rear end, is cut away, as designated by the reference-numeral A, and in forming the vtable I provide-upon` n the Vrear end at each side of the cut-away portion enlarged bosses 5 5, and secured uponV the top of-these bosses are bearingblocks 6 6, in which is journaled a main oper-I ating-shaft Y7. Upon the one end of the op- 8,1A one being loose on the sha t and the other tight on the shaft, and between these pulleyvwheels andthe table is mountedv a suitable n t j erating-.shaft 7 are mounted ulley-Wheels 8' pointing theend of the wire to `form nails of desired lengths.`

ily-wheel 9, The pulleys 8 8 are employed,

. whereby aL belt may-pass ,over the same and transmit motion to the nail-making machine from any suitable source of power'.

lCentrally between )the bearing-blocks 6.6 and upon the shaft 7 is secured the mainv camwheel 10, which isprovided with a cam-block `1 1, the object of which will be hereinafter more fully described. `At' each side of the main cam-wheel 10 and upon the main oper.- ating-shaft 7 are arranged the double camwheels 12 and 14. These cam-wheels, one of which is illustrated'in Fig. 6 of the drawings', carry aperipheralcam-block 15, and upon the outer side of each wheell are secured the camblocks 16. Upon the end of the' shaft 7 opposite the pulley-wheels 8 is secured a Vwheel 17, having formed 'therein a slot 18, and the object of this wheel and slot will be hereinafter referred to. Mounted upon the top of the table and centrally thereof is a plate 19, this plate being slotted upon its sides, as indicated at 20, whereby the same may be adjusted upon the top ofthe table and rigidly held in its adjustedposition by the bolts and nuts 21 2l. Theplate is provided longitudinally of its length with upwardly-extending flanges 22 22, forming a guideway for the header-plunger, which will now be described. The header plunger, as designated by the reference-numeral 23, is .provided with beveled sides 24,24, and overlying these beveled sides of the 'header-plunger are the` guide- IOO blocks which are secured by bolts 26 to the upwardly-extending anges 22 22, these guide-blocks permitting the header-plunger to slide within the guideway. The rear end of the header-plunger is provided with a block 27, which sets in a slot 28, formed in the end of the plunger, said block 27 being held therein by a bolt and nut 29, and this construction is employed, whereby the block 27 may be removed when it has become worn and a new one placed therein. The forward end of the plunger is provided with a boss 29, in which is secured the screw-threaded shank 30 of the header 40, said header having a tapered end 41, which is provided with a recess 42, and in the tapered end is formed a slot 43, which communicates with the recess 42. The header 40 is adjustable upon the screw-threaded shank 30 and is held by a screw 44. The plate 19 upon its forward end and at each side is provided with lugs 45 45, said lugs having formed therein apertures in which is rotatably mounted a shaft 46,r this shaft being provided with a crank 47, that is pivotally connected to a rod 48, which is secured, as indicated at 49, to one side of the plunger 23. Carried by the shaft 46 directly beneath the header 40 is an upwardly-extending -arm 50, which lies within the slot 43 of the header, and the end of the arm is adapted to extend slightly into the recess 42, the object of which will be more fully described in the operation of the machine. The plate 19 upon each side is provided with the bearing-blocks 51 51.

The reference-numerals 52 52 designate two standards, one of which is arranged at each side of the plate 19, preferably near the forward end thereof, and pivotally mounted upon the standards 52 52 by the threaded pins and nuts 53 53 are the oscillating arms 54 54, these arms being actuated by the camwheels 12 and 14. The rearwardly-extending portion of the arms 54 54 are bent inwardly, as indicated by the referenceenumeral 55, and the end of each arm is provided with an enlarged portion 56 56, which is cut away, as indicated at 57, to receive wheels 58 58, which are rotatably mounted upon the pins 59 59, carried by the enlarged portions of each arm. The forward end of each arm is tapered, as designated by the referencenumerals 60 60, and are contracted to form a lug 61 the object of which will be hereinafter more fully described. Upon the top of the table, and preferably near the edges of the rear end of the table, are mounted standards 62 62, and to these standards are secured springs 63 63, the loose ends of which are adapted to bear against the inwardly-bent ends of the arms 54 54, as clearly shown in Fig. 1 of the drawings. Upon the inside of each of the arms 54 54 are provided the screws 54 54 which are employed to limit the oscillating movement of the arms 54 54, these screws being adapted to bear against the bearing-blocks 51 51 when being adjusted and said bearing-blocks extending upwardly to a level with the said arms 54 54, as shown in Fig. 2.

The forward end of the table has its top cut away, as indicated by the reference-nu# meral 64, this cut-away portion being form ed centrally of the width, but adjacent the for'- ward end of the table, and at each side of the cut-away portion and upon the top of the table are mounted blocks 65 65, said blocks being provided with slots 66 66, through which screw-threaded pins 67 protrude and have secured upon their ends nuts 68 68, whereby when said nuts are loosened the blocks may be adjusted longitudinally of the length of the table. To facilitate the adjustment of the blocks 65 65, the forward end of the table is provided with the upwardlyextending arms 69 69, through which pass the screwbolts 70, the ends of these bolts being adapted to bear against the edges of the blocks 65 65, and by rotating said screw-threaded bolts when the nuts 68 have been loosened the blocks may be moved along the top of the table. Each one of the blocks 65 65 is provided with a vertical wall 71, and to said walls are secured the guide-plates 72, these guide-plates being similar in construction to the guide-plate 19, and in said guide-plates are adjustably mounted the knife-holders 73 The knife-holders are held within the guide-plates 72 72 by the guide-blocks 74 74, which are secured to the guide-plates by the bolts 75 75. The vertical walls 71 of each one of the blocks 65 are provided with slots 76 76 (reference being had to Fig. 12 of the drawings) and with a slot 77. The knifeholder, as illustrated in Fig. 9 of the drawings, comprises a block which upon its rear side and at one end thereof is cut away, as indicated at 78, to receive a knife 79, this knife being secured in the cut-away portion by a bolt 80 passing through the knife-holder and screwing into the knife. The opposite side of the knife-holder is provided with an cnlarged portion, being provided with a recess 82, into which is adapted to protrude the lugs 61 61 of each of the arms 54. To provide for the adjustment of the knives 79, I have mounted the knife -holders whereby they may be vertically and transversely adjusted in respect to the top of the machine. Each one of the knife-holders is provided with a slot 83 near its one end, through which a bolt 84 passes, and by loosening said bolt the knife-holders may be longitudinally adjusted within the guide-plates 72. '.lo adjust the knife-holders or knives vcrtically, l have provided each one of the guide-plates with an outwardly-extending arm 85, said arm being provided with a screw-threaded aperture 86, this arni being adapted to protrude through the slot 77 of the vertical wall 71. Communicating with the slot 77 is an aperture lZO l 87,'i`1'1'whici1 is located a thumbsrewss, that passes down through the'screwfthreaded ap` erture 86 of the arm 85. To insure a positive engagement between the verticalwall 71 and the guide-plate 72, I have provided the rear face'of the guide-plate with the stub-bolts 89,

which protrude.througlrthe'slots 76 and have i secured-on theirouter ends nuts 90. Y i

Between the blocks 65 65, `carriediby the.

top of thetable, and upon the forwardedge of the opening or cut-away portion 64 'is .mounted a channel-block 91, whichMis providedwith an' opening 92, through which the In the stock wire 93 is adapted to pass. channel-block 91 is mounteda guid`e-plate 94, this guide-plate being similar in construction to theguide-plates 19 and 72 with the eXception that the guideway of said plate is vertical, and in said guidewayare mounted the gripping-'blocks 95 and 96, said vgrippingblocks being retained in the guideway by the guide-blocks 97 97, which'are'similar to the guide blocks 0r plates v72,7and they are re' tained in their position by the screw-bolts 98 98. yThe upper gripping-block is Ladjustably mounted Within the guideway and is adjust.-v ed therein by a thumb-screw99, whichis car ried by an overhanging bracket 100, supported from the guide-plate 94. The lower gripping-block 96 is adjustably connectedby a `nut and bolt 101 to the-forward end of a bar 102. Thisfbar is mounted upon a pin 1 03, j ournaled inthe depending brackets 104 104, carried by the underneathv side of the topof the table. The rear end of the bar 102 is bifurcated, forming arms 105.105, and the end of each arm vis slotted, asindicated at l106,

side, and to said lug is pivotally connected a lever 112, this lever being provided Withinwardly-extending arms 113 113, in which is journaled a vertical roller 114, The wire 193 is adapted to pass between the rolls and 114, and to normally hold theroll 1 14 inen gagement with the Wire I have providedA the depending spring l 15, which 'is secured to the top of the bracket, as indicated at 1 16, and is,v

adapted to engage the leverllZ and prevent the outward movement of said lever. tween the bracket 109 .and the block Y91 is mounted the mechanism for feeding the Wire at predetermined times to the machine, .this mechanism consisting of an arm 117, which v4 of the drawings.

is slotted', as indicated at'118, 'and the arm is slidably mounted upon the 'outwardly eX'- tending arm 108. In the slot 118 of said armi.

is mounted partof the feedingmechanism for the wire 93, which consists of a gripping-bar; 119, that is pivoted, as indicated at 120, in av casing 121, said casing being secured in slotl 118 by any suitable means, and the casing is slotted upon its inner side, as indicated aty end a block 1 28, and the wire 93 is adapted to pass 'between the"c`asing 121 andthe block 12s. The arm 117 is contracted upon its one end to form a pin, and secured uponv this pin by a nut 129 is the end 130 of the'substantially L -i shaped rod` 131.'.V This rod extends rear' l wardly along'theone side of the machine and' 1 is adiustably secured by abolt and nut 132iV g in the slot 18of the wheel1l7. Y 1

brace which is securedto the top of the stand.

ards 52 52, said brace extending across theV machine, as clearly illustrated in Figs. 11v and Centrallysecured to said brace is a springv 134, this spring being bent saids'pring engaging the rear .endof thebar v102, as illustratedin Eig. 5 of the drawings.

The operation and manner of 'manipulate ing my improved machine for forming wire nailsis as follows: The wire from which the nails are made is fed between 'the rolls 110 and 114, thewire being passed through the slot 1 18 of the arm 1 17, through the opening 92 of the block 91, and to 'such a position that it will be gripped by the upper andilower grip ping-blocks. We Will assume that the ma chine is in such a position that these blocks will grip vvthe wire, and upon motion being transmitted to the main operating-shaft v7 said shaft is revolved, carrying with it its numerous wheels, one of which-namely, the cam-wheel 10-will revolve, causing the oam1 block 1 1 to strike the block 27, carried by the rear end of the plunger 23. As said wheel re volves the plunger will be moved forwardly until the header 40 has struck the end of the ISOA Aro

Wire and formed a head. A further revolution of the shaft releases the plunger 23, and the spring 134, which has been contracted, will expand and return said plunger to its normal position. Should the headed end of the wire which has been headed have a tendency to adhere to the header and substantially in the recess 42, which forms the head of the nail, the rearward movement of the plunger will, through the medium of the rod 48, shaft 46, and arm 50, release the end of the wire or the head of the nail from the recess 42 of the header, the rearward movement of the plunger causing the shaft 46 to revolve and move the arm 50 outwardly to disengage the head of the nail from the header. Vhile this operation is taking place the wire has been held between the upper and lower grippingblocks, this being facilitated by the camblocks 15 15 of the wheels 12 and 14 respectively engaging the rollers 107 and 107, carried by the bifurcated bar 102, and as the cams engage the rollers the forward end of the bar 102, which is connected to the lower gripping-block, will be held upwardly, causing the lower gripping-block to engage the upper stationary gripping-block. When the shaft 7 revolves to release the plunger, a further revolution releases the bar 102, and a still further revolution will, through the medium of the wheel 17, reciprocate the rod 131, this movement of the rod carrying the arm 117 rearwardly, and the gripping bar 119 will travel over the surface of the wire until the arm 117 has been carried such a distance as Will be permitted by the crank connection of the rod 131 in the slot 18 of the wheel 17, at which time the rod 131 will be carried rearwardly, and the gripping-bar 119 will impinge against the wire 93 and carry it forward with the movement of said arm 117, to which the bar 131 is connected. The gripping of the bar 119 against the wire 93 is facilitated by the adjustable block 128, which may be adjusted to cause said gripping-bar to firmly grip the wire; but for any reason or other should the gripping-bar fail to grip the wire the lever 125 may be swung to cause the cam-shaped lug 124 to engage the grippingbar 119 and further force said gripping-bar into engagement with the wire 93. The amount of wire carried into the machine by the mechanism just described is governed by the position of therod 131 within the slot 1S of the wheel 17 the slot 1S and the bolt and nut 132 being provided, whereby the rod 131 may be adjusted within the slot 18, and it `ceive the same.

erases",V

will be seen by this construction that dii'lerl ent lengths of wire may be fed into the machine for different lengths and weights of nails. The wire having been headed and fed into the machine, the arms 54 54 are actuated by the cam-blocks 16 16, carried by the sides of the Wheels 12 and 14, respectively, and as said cam-blocks strike the rollers 5S 5S the rear end of the arms 54 54 will be moved outwardly or spread apart, this movement causing the forward ends 60, carrying the lugs 61 61, to move inwardly, and as said lugs lie in the recesses 82 82 of the knife-holders said knife-holders carrying the knives 79 will be moved inwardly and the sharp tapered edges of the knives will sever the wire 93, simultaneously pointing the same, which is facilitated by the beveled cutting edge of the knives. Upon the wire being sheared the desired length it drops through the opening 64 of the top 1 of the table and may descend into a suitable receptacle placed therebeneath to re- As the shaft 7 continues to revolve the rollers 5S 58 pass from 0H the cam-blocks 16, and the springs 63 63 will return the arms 54 54 to their normal position, and the operation just described will again be repeated,

lt will be observed from the foregoing description, taken in connection with the d rawings, that the majority of the mechanism employed by me to form wire nails is adjustable, l employing these adjustable features whereby the mechanism may be adjusted to produce different sizes and weights of nails with as great a rapidity as desired.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

The combination in an organized nail-making machine, of gripping means, a reciprocating plunger, a header carried by said plunger and'having a concavity in its head and a slot leading into said concavity, with an ejector seated in said slot and adapted to slide in the same and eject a nail from the head of the plunger on the return movement of the plunger, and means operable by the return movement of the plunger for effecting the sliding movement ofthe ejector in the slot.

ln testimony whereof I aflix my signature in the presence of two Witnesses.
